Unsupervised Learning of Object Keypoints for Perception and Control., Lin, Zhixuan, et al. In addition, object perception itself could benefit from being placed in an active loop, as . a variety of challenging games [1-4] and learn robotic skills [5-7]. Human perception is structured around objects which form the basis for our higher-level cognition and impressive systematic generalization abilities. /St To achieve efficiency, the key ideas were to cast iterative assignment of pixels to slots as bottom-up inference in a multi-layer hierarchical variational autoencoder (HVAE), and to use a few steps of low-dimensional iterative amortized inference to refine the HVAE's approximate posterior. . The fundamental challenge of planning for multi-step manipulation is to find effective and plausible action sequences that lead to the task goal. We show that optimization challenges caused by requiring both symmetry and disentanglement can in fact be addressed by high-cost iterative amortized inference by designing the framework to minimize its dependence on it.
